PLOW-POINT.

SPECIFICATION forming part of Letters Patent No. 397,855, dated February 12, 1889.

Application filed February 18, 1888. Serial No. 264,498. (No model.)

To to whom it may concern;

Be it known that 1, JAMES HAWKE, a citizen of the United States, residing at Long Run, in the county of Licking and State of Ohio,

have invented certain new and useful Improvements in Plow-Points; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains IO to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to plow-points that have a grooved opening in the rear upper portion situated midway between the share and landside, the opening having thin flanged edges that have somewhat of a spring terminating in a socket contracted at the point, so that the socket is slightly wedge-shaped, by means of which the point is held to work by frictional contact the more firmly as it is forced upon the plow by pressure incident to plow- 111g.

Another feature of my invention is to make the point with a rearwardly-extended share and heel or landside, by means of which the plow has a steadier movement, more especially by reason of the extended landside, the extended share being adapted to fit over a worn-out share on an old mold-board. Thus I am able to use a plow, that would otherwise become soon worn in use, an indefinite time. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a perspective view of part of the plow turned on edge on the landside, with my point attached. Fig. 2 is a perspective view of the top of my point, showing the socketed opening with the flanged edges. Fig. 3 is a sectional view on the line a b, Fig. 1.

Heretofore points have been made to fit over worn-out-plows; but they havebeen firstheated and shrunken in place, as in Patent No. 154,139, to J. F. Herrig, where the inventor also uses clasps; or they have been fitted over a worn-out plow by means of a socket in the point and then held in place by bolts, as in Oliver, No. 220,619, or Trissler, No. 179,973, or in Odell, No.

158,512. Other means for holding socketed points in place have been used; but in my invention I obviate all these, and my point is held in place by frictional contact alone. This object can be obtained by casting the point with a socketed opening gradually contracted, having thin beveled edges that have something of a spring to them, so that as the point is crowded onto the plow it is held by the springing edges of the flanged opening.

A is the slotted opening; a, the thin flanged edges that by frictional contact aid in holding the point in place.

B is the socket in which the plow fits when the point is in place. (Denoted by dotted lines, Fig. 2.)

E is a slotted opening, of V shape, in the upper face of the point, differing somewhat from those shown in other figures, and applying to the points that are used on bull-tongue or shovel plows, where the extended landside or heel and share are not needed. It will be noticed, also, that aside from the beveled upper and lower edges of the socketed opening of the point the point is rounded outwardly, so that the earth easily slides off, and the plow does its work with less friction than otherwise.

F is the point beyond the socketed flanged opening, and is cast solid or otherwise so constructed.

h represents the extended share, which may be made two, four, or six inches in length, to suit the particular style of plow upon which it is to be used.

j is the extended landside or heel, to which I attach great importance in the use of large turning-plows, as it helps to hold the plow steady with a minimum amount of jerky oscillating motion.

- t is the extended sole or bottom of the point, which by its length of bearing aids in holding the plow-point to its place, and by which construction there is less liability of displacement.

These points can be easily placed upon or removed from a worn plow without taking the plow to a smithy, thus making a simple, convenient, and effective point with little cost.

Having thus described my invention, what I 100 claim as new, and desire to secure by Letters securely held in place, sulmtumnxiall as de- Patent, is seribed. 1 o
